I have always expressed and given her a bottle maybe once or twice a day and then a bottle of formula as a top up on a night and never had any problems breastfeeding, but these past few weeks we go through the same trauma for each feed, she just wont accept my boob anymore, sometimes if i give her a dummy then swap it for my boob she will take it but not for long, i have tried every different position there is and i just end up giving up and giving her a bottle. There is the odd occasion that she will accept it during the day and she feeds like a dream and through the night we have no issues at all. I really dont want to have to express in advance and sterlise equipment all the time I just want her to accept me, any advice?
